Recent studies have shown that overexpression of pro-inflammatory cytokines (e.g. IL-6, IL-12, IFN- γ, IL1B, monocyte chemoattractant protein-1 (MCP-1), and interferon gamma-induced protein 10 (IP-10) in serum is strongly correlated with multiple organ failure in patients with COVID-19 disease [10]. The gene discussed is CCL2; the disease is Multiple Organ Failure.
